The muscle decreases in muscle length during contraction but tension is the same?
Isotonic contraction
What is muscle treppe?
•Increased contraction in response to multiple stimuli of same strength
Do arterioles have valves?
No; arteries (and arterioles) depend on smooth muscle contraction, whereas veins (and venules) have valves.
Hypocalcemia will cause the heart rate to?
slow down or will cause bradycardia. calcium is essential in muscle contraction.
Why does walking prevent stagnation of blood in the legs?
The venous circulation of the legs requires muscle contractions to assist with blood return. Walking helps provide this muscle contraction.
Quivering or spontaneous muscle contractions especially of the heart is called?
fibrillation
Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone
Explain a muscle spasm in terms of recruitment of muscle fibers?
A muscle spasm is the spontaneous recruitment of muscle fibers. The resulting contraction is usually painful, but it typically resolves very quickly.
What contraction that shortens the muscle but does not increase tension is called?
It is called concentric isotonic contraction.
What is The contraction of muscles for no obvious purpose called?
An involuntary muscle contraction is called a spasm.
True or false When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the contraction is called a muscle twitch.?
true
A maximal sustained muscle contraction is called a?
tetanic contraction.
What is called a constant muscle contraction?
Tonus is the continous baseline muscle tone in the body.
When a muscle contracts and relax it is called?
Spasm
A contraction that causes a muscle to lengthen rather than shorten is called?
An eccentric contraction is one that causes a muscle to lengthen.
What is a waste product of muscle contraction called?
Creatinine
What is a painful contraction of a muscle called?
Often it is called a cramp.
